Bob,

BTW:
the only lines of code in the test project I ran were the includes for you units.
You can't just compile the DT_INTS-14.BAS file by itself. I suspect that's why you're getting this particular error.

See this thread for a detailed explanation on how to use DT_INTS-14 http://www.picbasic.co.uk/forum/showthread.php?t=3251 along with some easy examples.

I've used DT_INTS-14 in a lot of apps, including my new serial LED module, and they do work as advertised, but you will need to read/try a few of Darrels' examples to understand how to use them in your own applications.
